The invention relates to a method for exchanging data between a navigation device and a data cloud regarding a route (300). The method includes the steps of: storing the route (300) in the data cloud and in the navigation device, assigning a route identifier for the route (300) in the data cloud, transferring the route identifier from the data cloud to the navigation device, and transmitting additional data between the navigation device and the data cloud, each of which is related to a route segment (305) of the route (300) and is transmitted together with the route identifier.
Legal claims defining the scope of protection, as filed with the USPTO.
3. The method according to claim 1, wherein the route (300) is calculated with the navigation device and route data characterizing the route (300) are generated with the navigation device and transferred to the data cloud.
4. The method according to claim 1, wherein the route (300) is calculated in the data cloud and route data characterizing the route (300) are generated in the data cloud and transmitted to the navigation device.
5. The method according to claim 1, wherein the additional data transmitted from the navigation device to the data cloud each relates to a route segment (305) traveled and includes weather conditions on the route segment (305), traffic conditions on the route segment (305), an energy consumption for traveling the route segment (305), a time duration for traveling the route portion (305), an actual length of the route portion (305), a position of the route portion (305) on the route (300), a time of reaching the route portion (305), and/or a time of leaving the route portion (305).
6. The method according to claim 1, wherein the additional data transmitted from the navigation device to the data cloud are stored in the data cloud and associated with the route identifier.
7. The method according to claim 1, wherein the additional data transmitted from the data cloud to the navigation device each relates to a route section (305) to be travelled and comprises a prediction of weather conditions on the route section (305), traffic conditions on the route section (305), an energy consumption for covering the route section (305), a time duration for covering the route section (305), a time of reaching the route section (305) and/or a time of leaving the route section (305).
8. The method according to claim 1, wherein the additional data are transmitted from the data cloud to the navigation device only in response to a request sent by the navigation device to the data cloud.
9. The method of claim 8, wherein the request comprises the route identifier and characterizes a route segment (305) to which the request relates.
10. The method according to claim 1, wherein in case a route identifier unknown to the data cloud is transmitted to the data cloud by the navigation device, the method further comprises sending an error message to the navigation device by the data cloud.
